hi team,

In Page 8 of ADS8345 datasheet, a figure is change in BPZ vs temperature.

what is the BPZ, is it bipolar error and offset error?

thank you!

    Hi Felix,

    For the ADS8345, that change in BPZ figure versus temperature is actually depicting drift, not so much offset.  BPZ is the point at which you get code 0x0000 out with XYZ voltage in.  In other words, how far from the 'ideal code' are you with XYZ = 0.000 volts input to the device.  From there, how much variation is there in XYZ over temperature?
